N850hk1

Hello guys.

My laptop fan is stupid. Everytime i plug in the charger to my laptop and im watching Netflix or surfing on the internet my laptop fan is makeing alot of noise. Also my laptop get rly hot when i play a game is there any fix to that? besides new thermal paste and undervolting?

I hope that someone can help me, with the problem.

Sorry for my bad spelling, my english is not that good.

 

What are your temperatures? Did you test that?

 

around 90 + when most hot (CPU) and around 75 when browsing

 

Could you test your laptop (in autofan mode) with aida64 extreme (stability test cpu and gpu) for 30 minutes?

 

Sure. ill be back in 30 min. do you have any idea why my fan is make noise every time i plug in the charger? is so weird. when it only runs on battery there no problem and the fan is quite, but everytime i plug in the charger it start makeing noise.

 

Avg. 93 cpu. Coldent see The data for The gpu but as far as i remeber is not that hot at all.

 

Could you post a screenshot of that test?
You could use techpowerup gpu-z for gpu temperatures and hwinfo for cpu temperatures

Where did you test it? Desk? Wood surface?

 

ok im back with results now.

a weird thing is that when i plug in the charger to my laptop then after 30 sec to 1 min the tempeture raise with 12-14
degrees.

all tested on a desk

Those results are really bad
Hi! @tanzmeister
What do you think about these numbers?

 

definitely RMA it!

 

CPU voltage looks good, so I assume it's a good chip. the heatsink could be a faulty one, I have already seed a few. could be a bad paste job too

is this a double heatpipe revision or single?

 

What does that mean?

Im noob so im sure What a heatpipe is. But if it What i Think it is. Its a double heatpipe because The cpu get heat out on The back of The laptop and for The gpu on The Right side of The laptop

 

It is likely because you have different power profiles set for battery power to mains power.

Depending on your OS version, either click on the battery icon on the bottom right of your windows desktop, or right click and go to "Power Options". Check which power plan is running on both battery power and mains power from the PSU. Usually, when you plug the PSU into the laptop it will switch to Balanced or High Performance - when you disconnect the PSU it will switch down to either Balanced or Power Saver. These different levels of power plan will affect the clock frequency of the CPU and GPU, which will result in either an increase or decrease in temperatures.

If you have a look through these files, you can see that the CPU and GPU clock are half the value on battery power than what they are running at on PSU power. By itself, this isn't cause to RMA the laptop - it's normal and you can also adjust each power plan to suit your requirements in "Change plan settings

 

98C on CPU is not the cause to RMA the laptop? come on!

with just silly AIDA64 CPU test? not even a FPU test?

I am sure you just did not notice the temperature on the screenshots, otherwise you would surely confirm the must of RMA here , am I right?

 

Thanks for the unnecessary bucketload of sarcasm, I think you quite clearly know that I didn't say 98C on the CPU isn't a reason to RMA the laptop. But actually see below for further data on this!

I specifically quoted only the comments made by @tiptop91 regarding the different behavior on battery vs mains PSU power. No one had replied to these comments or explained what could cause this behavior so I thought it might be a good idea to explain ;-)

Not that it has a bearing on my post, as I stated I was only commenting on the battery vs PSU questions, but no I didn't look at the temperatures in the stress test - was only looking at the figures in the download link.

If we had Prime95 (Blend) and Furmark (stock FHD settings) CPU and GPU temperatures then I could compare directly with our R&D results we hold on file for both the original HS and the new HS design that we asked for. It's quite possible that @tiptop91 has an original design HS.

What was the GPU running at temp and clock speeds? Of course I know that Prime95 is more demanding than AIDA64 CPU part of the stress test, but with no GPU temp results from this 30 minute test we only have half the story. I can say that Prime95 and Furmark simultaneous run give you 91C - 98C in this chassis (in fact Prime95 by itself runs to max 98C) but in the case of Prime95 + Furmark the CPU clocks just less than 600MHz lower than @tiptop91 AIDA64 tests at 2.85GHz vs 3.4GHz.

 

So what should i do? please answer in simple noob way so that i can understand it

 

You should add a screenshot with gpu-z with gpu temperature when you make your test.

You posted cpu temps here

There are three different versions of cooling system for your n850hk1
-1heatpipes cpu +1heatpipe gpu
-2heatpipes cpu+1 heatpipe gpu
-2heatpipes cpu+2 heatpipes gpu
what's yours?

 

Did not mean to be rude or anything.

 

Return it to the seller for replacement

 

A normal performing N8 with AIDA really pulling 100% ( CPU+FPU+GPU ) should not even throttle, doesnt matter what cooler you got (first version or second).
I never even seen anything like that, are you sure you have your coolers in place? I doubt they are making proper contact.
We build like 3 or 4 a day, and any unit reaching anything close to 90ºC gets back in line for re-inspection.

Just pulled one example for the test files of a random order with old cooler version (single pipe):
http://uploads.im/RCeN4.jpg

30 minutes, 100% CPU/FPU/GPU
Max CPU Temp: 87ºC
Max GPU Temp: 70ºC

And these are not even anything special, just the old N850HK1 with 1050Ti and single pipe cooler.

 

I have seen a couple of badly factory soldiered heatsinks for n850.

but as you have mentioned it.. n85 with single pipe can easily go above 90 in simple XTU memory test after 15minutes with auto fan control. that's with Gelid Extreme TIM or Grizzly Kryonaut.

unless you undervolt the CPU... and that's what you have there according to your screenshot.

I also don't understand why your clocks are just 3200? not 3400? lowered TDP value?

 

I have this computer and it does run hot out of the box. Try these things:

Make sure Windows 10 and Clevo Control Center are not in "Performance" mode. If they are, set Windows to "Balanced".

Turn down max CPU to 98%. This computer will never run at 100% with 100% CPU without temps in the high 90's.

Repaste the CPU and GPU. I used Arctic MX-4 and it lowered the idle temp by 10°C.

 

by lowering to 98% CPU in windows you probably turn off turbo boost completely.

and remember: Clevo is only a hardware manufacturer, so each Brand is responsible for the build and the paste job, so the results can vary a lot!

also there were 3 revisions of the cooling system, together with the motherboard, so it's important to know which one exactly do you have.

 

That's correct, the Turbo Boost is most likely disabled. You can run the CPU at 100%, but the system temps will run in the very high 90's. Personally, I think running any computer a couple degrees below the thermal threshold is a bad idea.

My laptop is a Eluktronics. It had a very poor thermal paste job on the CPU, the 10°C temp improvement at idle is a pretty good indication of that. The CPU cooler is the two pipe version. I don't believe the motherboard is defective because, aside from the overheating issue, the computer works fine.

I have a bit of experience with heat sinks as an aviation electronics technician, my opinion is that the CPU heat sink is inadequate to keep the processor within an acceptable temperature when running at full load. Technically, you can run it at the advertised speed, practically you can not. This is a corner they cut to get higher end components in a certain price point package.

 

how do i find out how many pipes my laptop has?

 

Post here a high resolution photo of the bottom under some good light

 

Most of the machines of this model that went through my hands hardly reach 80C in XTU memory test, which is harder than CPU stress test

 

My laptop will hit 98°C rendering 1080p video every single time if the CPU is set at 100%, even with the Arctic MX-4 thermal compound. You said "most" of these computers in your experience run within acceptable thermal ranges. That would add quality control questions along with poor design and/or construction. Perhaps the N850HK1 vendors should change "most" of the retail price.
Sorry for the disconnected quote. The constant ad loading make this forum difficult to use.

 

Here is a picture of the bottom of my laptop.

Btw i found a solution to my problem. In CCC i choise quite and under power conservation i choose power saveing. Now my laptop is cool (60 degrese + -) and the fan dont make any noise now.

On all The test i did i was using quite and balenced in ccc, donno if that why my pc was getting so hot?

 

Most = vast majority. There is no 0% defect rate, and variables can arise after a product leaves QCs hands, unfortunately.

 

Mine (the i7 version) reach high 90s on Aida64 bench with Auto Fan et Performance mode. On charger.Turbo boost is desactivated.
this laptop seems to run hot under heavy cpu load, but for everyday use I don't have any problems (web browsing is often on fanless mode). Mine have the stock paste, I guess I could save some °C by changing it but I'll wait a bit

 

that is dual pipe system, 60 degrees for underpowered 7700hq in this laptop is too much! I suggest you to return this laptop to the manufacturer.

 

that really rises the question about the quality control of the Brand you have bought your machine from. who knows what they could have done with it? why other Brands that offer Clevo should suffer from this? and Clevo is not the one to blame here either.

the Brand I am connected to never lets out any laptop that has any signs of overheating or throttling, built on the same chassis others Brands do.

I say "most" because those that did not match the QC where RMA'd back to the KAPOK factory.

please do RMA your machine as well!

 

Under normal circumstances, I would have RMA'd the computer immediately. Unfortunately, I am traveling, the computer is loaded with information that would have to be deleted before returning, so returning the computer is not a viable option.
Like the Prostar Representative said, most of the computers are probaby good. I took a gamble I would get one of those good ones and lost. The Eluktronics technician was the one who told me I needed to dial down the CPU to prevent overheating. That would have been nice to know before I purchased it. I repasted the poor factory thermal paste job(most of the thermal paste was off the chip on the motherboard) which improved cooling by about 20%, but this improvement is deemed "tinkering" by Eluktronics and voided the warranty.
I think Clevo computers are pretty decent; if you get one of the "good" ones and you can find a reseller that does not charge extra for a computer that works properly. I was told all computers were tested before shipping. Mine either slipped through the cracks(poor quality control), or Eluktronics feels running a laptop computer at 98°C is OK. I have a different opinion and a new computer with no warranty that I will try to improve on my own, which I think I can do.
That's the way it goes.

 

Which version do you have (number of heatpipes) ? there was a guy on the N850 owner loundge trying to buy new heatpipes to lower temps, I don't know if he managed to get some

 

It was me, and at the moment I'm waiting for https://ru.aliexpress.com/item/Mult...lgo_pvid=e33b7c73-810a-4032-a6e9-1edfea376b95 to add another cooler and a heatsink to the place of the 2.5 "drive.

 

Replacement heatsinks for this model are hard to shop for, also; don't think a lot of resellers stock and sell them standalone.

 

Check with @clevo-extreme for those heatpipes replacement

 

Since Clevo is a brand of computer that a laptop enthusiast would buy, it would be nice if one of these Clevo vendors would cater to that part of the market and offer upgraded and/or replacement parts for those people who like to build and upgrade their own computers. Since there are no real "do it yourself" laptop computer opportunities, this would be a new market and a fresh business opportunity.

 

Why can not anyone just sell a cooling system with two heat pipes? I wrote to almost all resellers here, and no one could help ...

 

there aren't n870hk1 with a different cooling system, that is the reason

n870hk1 cooling system


n870hp6



there is a new version of n850hk1 with a different cooling system

first version n850hk1


second version of n850hk1


third version of n850hk1


n850hp6

 

Because there was a motherboard change for the n850hk1 and the new cooling does not fit the old motherboard! I have not yet seen n870hk1 with new cooling though.

 

are you talking about n870hp6 cooling system?

 

@Meaker@Sager
do you a photo for the cooling system of th n870hp6?

 

Even if manually modify it?

So-so news. I was hoping for the possibility of installing a factory version of improved cooling system.

 

IIRC it's the same setup as the NP7850 just with longer heatpipes for the GPU.

 

Can anybody provide me with a CPU heatsink from n850hp6? It is almost the same with n870hk1.

 

are there 2 heatpipes for cpu heatsick in that n870hp6?
are n870hp6 cpu heatsink and heatpipes compatible with n870hk1?

 

I have not done any measurements so cannot say. It sure looks similar.
